A discharge plate 703 is fixedly connected to one side of the screening plate 7, and the discharge plate 703 is arranged below the tail end of the screening cylinder 8. A screening cylinder 8 is provided above the screening plate 7, and the screening cylinder 8 is movably connected to both ends of the support frame 6 in an engaging manner.

[0023] Specifically, with this arrangement, when in use, the support frame 6 is installed on the cleaning tank 1 to support the screening plate 7 and the screening drum 8, the cleaning tank 1 is filled with liquid for cleaning fruits and vegetables, and the liquid is circulated by an external water pump and other equipment, thereby achieving continuous cleaning of the fruits and vegetables, the servo motor 4 on one side of the cleaning tank 1 provides power to the transmission mechanism 5, and the transmission mechanism 5 drives the rotation of the cleaning drum 2, so that the agricultural products in the cleaning tank 1 are fully turned over during the cleaning process, thereby cleaning and separating impurities such as mud or pesticide residues sticking to the surface of the fruits and vegetables, and at the same time, the rotation of the cleaning drum 2 transports the fruits and vegetables in the cleaning tank 1 to the bottom of the roller 11, thereby facilitating the scooping bucket 13 to scoop fruits and vegetables of different sizes into the screening drum 8 for screening and separating impurities, and the fruits and vegetables of different sizes and impurities screened out are classified and discharged through the discharge box 701, the discharge port 702 and the discharge plate 703.

[0024] like Figure 1 - Figure 5 As shown, in this embodiment, a transmission shaft 801 is provided at the inner center of the screening drum 8, and the transmission shaft 801 is transmission-connected to the servo motor 4 installed on one side of the support frame 6, the screening drum 8 is fixedly connected to the transmission shaft 801 through a connecting rod, and the screening drum 8 is provided with screens of different specifications, and a transmission mechanism 5 is fixedly installed on the other side of the support frame 6, and the transmission mechanism 5 and the transmission shaft 801 are transmission-connected. A conveying plate 10 is fixedly connected above the transmission mechanism 5, and a threaded conveying rod 9 is movably mounted in the conveying plate 10, and a transmission disc 901 is fixedly connected to one side of the threaded conveying rod 9, and the transmission disc 901 is transmission-connected to the inner side of one end of the screening drum 8;

[0025] Specifically, through this arrangement, when in use, the servo motor 4 on the support frame 6 is operated to provide power to the transmission shaft 801, so that the screening drum 8 can be connected to the transmission shaft 801 through the connecting rod and rotated to screen the agricultural products. The vegetables and fruits of different sizes in the agricultural products are screened through the screens of different specifications on the screening drum 8, and the impurities therein are screened and separated from the vegetables and fruits. Secondly, the transmission mechanism 5 on the support frame 6 is transmitted through the transmission shaft 801, and then the transmission mechanism 5 provides power for the connecting shaft 1101 to operate. Since the transmission disk 901 is in contact with the inner side of the screening drum 8 for transmission connection, when the screening drum 8 rotates, it drives the transmission disk 901 to rotate synchronously, and then the threaded conveying rod 9 conveys the vegetables and fruits discharged from the scoop 13 into the inner side of the conveying plate 10 into the screening drum 8.

[0026] like Figure 1 - Figure 5 As shown, in this embodiment, slide rails 3 are fixedly installed on both sides of the upper part of the cleaning tank 1, and a slide table 301 is movably installed on the inner side of the slide rail 3. A collection cylinder 302 is placed on the upper side of the slide table 301, and the collection cylinder 302 is used to receive the discharge of the discharge port 702;

[0027] Specifically, through this setting, when in use, the collection cylinder 302 is placed above the slide 301, and the limit bar above the slide 301 is used to prevent the collection cylinder 302 from tipping over during the movement and material collection process. By pushing the slide 301 to slide between the slide rails 3, the collection cylinder 302 can be moved to the bottom of the discharge port 702 to collect the discharge material.

[0028] like Figure 1 - Figure 5 As shown, in this embodiment, one end of the cleaning tank 1 is fixedly connected to a roller support frame 101, and a roller 11 is provided above one end of the cleaning tank 1, and a connecting shaft 1101 is fixedly installed at the center of the roller 11, one side of the connecting shaft 1101 is engaged and movably connected with the roller support frame 101, and the other side of the connecting shaft 1101 is engaged and transmission-connected with the transmission mechanism 5 on the support frame 6, and a scoop 13 is equidistantly installed around the outside of the roller 11, and a baffle 12 is provided between the scoop 13, and the baffle 12 is engaged and fixedly connected with the roller 11, and both the baffle 12 and the scoop 13 are arranged in a porous mesh shape;

When the roller 11 rotates via the transmission mechanism 5 on the connecting shaft 1101, the scoop 13 rotates accordingly, thereby scooping the fruits and vegetables cleaned and conveyed through the washing drum 2 in the washing tank 1 into the scoop 13. When the scoop 13 rotates to the highest point of the roller 11, the fruits and vegetables fall into the conveying plate 10 through the opening provided on the scoop 13 along with the baffle 12. Since both the baffle 12 and the scoop 13 are arranged in a porous mesh configuration, when the roller 11 rotates, the liquid used to wash the fruits and vegetables in the washing tank 1 can be prevented from being brought into the conveying plate 10. At the same time, impurities in the fruits and vegetables are preliminarily separated, effectively improving the screening efficiency and cleanliness.

[0030] It should be noted that when using the present invention as a pre-processing and screening device for agricultural products, first, the support frame 6 is installed on the cleaning tank 1 to support the screening plate 7 and the screening cylinder 8. Subsequently, the liquid for cleaning fruits and vegetables is injected into the cleaning tank 1, and the liquid is circulated by an external water pump and other equipment to achieve continuous cleaning of fruits and vegetables. The servo motor 4 on one side of the cleaning tank 1 provides power to the transmission mechanism 5, and the transmission mechanism 5 then drives the cleaning cylinder 2 to rotate, ensuring that the agricultural products in the cleaning tank 1 are continuously cleaned during the cleaning process. The fruits and vegetables are fully turned over, thereby cleaning and separating impurities such as mud or pesticide residues on the surface of the fruits and vegetables. At the same time, the rotation of the cleaning drum 2 transports the fruits and vegetables to the bottom of the roller 11. The servo motor 4 on the support frame 6 drives the transmission shaft 801, which also drives the transmission mechanism 5 on the support frame 6. The transmission mechanism 5 provides power for the connecting shaft 1101. The transmission disk 901 is in contact with the inner side of the screening drum 8 for transmission connection. The roller support frame 101 provides limited support for the connecting shaft 1101 and the roller 11. When the roller When the connecting shaft 1101 of the transmission mechanism 5 rotates, the scoop 13 rotates accordingly, and the fruits and vegetables cleaned and transported in the cleaning tank 1 are scooped into the scoop 13. When the scoop 13 rotates to the highest point of the roller 11, the fruits and vegetables fall into the conveying plate 10 along with the baffle 12. When the screening drum 8 rotates, the transmission disk 901 rotates synchronously, and the threaded conveying rod 9 conveys the fruits and vegetables in the scoop 13 to the screening drum 8. The transmission shaft 801 drives the screening drum 8 to rotate and is connected to the transmission shaft 801 through the connecting rod to achieve the screening of agricultural products. The different specifications of the screens on the separation cylinder 8 separate the fruits and vegetables of different sizes and screen out the impurities. The fruits and vegetables of different sizes and impurities screened out are classified and discharged through the discharge box 701, the discharge port 702 and the discharge plate 703. The collection cylinder 302 is placed above the slide 301, and the limit bar above the slide 301 is used to prevent the collection cylinder 302 from tipping over during the movement and collection process. By pushing the slide 301 to slide between the slide rails 3, the collection cylinder 302 is conveniently moved to the bottom of the discharge port 702 for discharge and collection.
